Now, I'm going to to do the above conversion for second basemen. Table 1
below contains the following information for 22 MLB second basemen 800
or more innings in 2012:

Inn = Innings

RZR = Revised Zone Rating

OOZ = Out-of-Zone Plays

PIZAA = Plays in Zone Above Average

OOZAA = Out-of-Zone Plays Above Average

PMAA = Total Plays Above Average

RSAA = Runs Saved Above Average

The MLB Runs Saved Above Average leader was Cubs second baseman Darwin Barney +23 follwed by the Yankees' Robinson Cano (+18). The worst by far was Rickie Weeks of the Brewers (-34).

Omar Infante, who played for the Marlins and Tigers finished fifth with +12 RSAA. Some fans may be skeptical about Infante because he makes a lot of errors - second highest in the majors with 17 in 2012 - but he also makes plays. Infante was especially good at turning balls hit into the second base zone into outs finishing 12 plays better than average. He was also five plays above average outside the zone. Other advanced statistics support his being a strong defender as he was +6 on Defensive Runs Saved and +4 Baseball Prospectus' Fielding Runs Above Average.
